What are some methods one could use to separate two substances in a mixture?

A two phase mixture is a mixture of two different states of matter, for instance a mixture of a solid and liquid, or Gas and liquid
i.e. a soft drink contains both liquid (water) and gas (carbon dioxide)
One way you could seperate a gas/liquid mixture is by heating it and capyuring the carbon dioxide
One way you could seperate a solid/liquid mixture is to filter the suspension so you get the solid particles caught in the filter paper and the liquid goes through the filter paper

boil of some of the liquid (this is common when dealing with water or liquids with low boiling points).
use a strainer and pour of the liquid and strain the solid out of the mixture
you can add some chemical to the mixture so that a reaction occurs and a precipitate forms (the precipitate is usually a solid).

How do properties help us identify substances?
If you wish to separate the constituents of a mixture, knowledge of the properties the constituent substances will help you figure out how to go about separating them. If you have any property (solubility in water, for example) that applies to at least one of you substances, and doesn't to another, you can use the property to separate them. If you wish to separate a solution, knowing the solubility curves of each solute will allow you to separate by changing the temperature. For example, Potassium nitrate has a much higher solubility in water than sodium chloride at high temperatures, but at or near zero degrees Celsius, it has much less. So, if you had a solution of sodium chloride and potassium nitrate, you could lower the temperature drastically and most of the potassium nitrate will precipitate. This is but one example. If you have a solid mixture, and a certain number of the substances in it will dissolve in water (or any other solvent), washing the mixture with the solvent will dissolve those, leaving everything else behind (you could filter the solvent out to separate the substances which don't dissolve) If your substances are physically different in size, you could pass the mixture through a sieve (for example, to separate sand and gravel). If one of your substances is magnetic, but others aren't, you could use a magnet to separate them.
Heterogeneous matter composed of two or more pure substances each of which retains its identity and specific properties?
I believe you are talking about a mixture. A mixture is a physical blend of two or more substances where each substance retains its own properties. Since they keep their properties, mixtures can be separated into their original individual substances. Example: If you had a mixture of salt and sand, you could separate them by pouring the mixture into a container of water. Salt is soluble in water and will dissolve. You can then pour the salt water through a filter, capturing the sand. Then, by evaporating the water, the salt will be left.
How could you separate a mixture of small pieces of copper?
add alcohol
What are Substances that aren't chemically combined are?
Elements, I think that's what you're asking. Could be the inerts, not sure. I think you are asking about a solution, or a homogeneous mixture. This is when something is not chemically bonded, but very well mixed. The solution will not separate over time, like a heterogeneous mixture.
If you have a mixture of gravel and sand and salt and iron fillings what properties of these substances could you use to separate the mixture and how would you use those properties?
Particle size, solubility and magnetism. The iron filings can be separated with a magnet, the salt by disolving in water, and the remaining sand and gravel separated by simple screening.
If you have a mixture of substances with different - sized molecules. How could you separate them?
pour the mixture through a filter that will let the smaller substance through, but not the larger one.
How do you separate oxygen ammonia hydrogen mixture?
Various methods could be used to separate such a mixture. However, one suitable method which is widely used for separating gas mixtures is fractional condensation. This method relies on differences in boiling points to separate the components.
If you made a mixture of iron fillings and salt how could you separate that mixture into its 2 original substances?
Place the mixture in water. You recover the iron once the salt dissolves. Then allow the water salt mixture to dry and allow salt crystals to reform.

How could you separate the components of homogeneous mixture to the components of heterogeneous mixture?
you can answer that by your mind. you can separate it by using a wire WIREGAUSE.
How could you separate gold from a mixture of zinc and gold?
We could add HCl to the mixture of Zinc and Gold and see which one appear to separate first.

How do you separate substances in a mixture?
yes because a fractional distillation silly, different boiling points!
Could you use filteration to separate a mixture?
sure, why not.
How many phases are present in a mixture of water sand and oil. How could you separate this mixture into individual substances.?
Sand would lay on the bottom, water would occupy the middle, and oil would float on the top. So, in a tall tube of all three substances, careful extraction from three heights of the tube would separate as required.
What materials can be used when separating a mixture?
The physical properties of substances can be used a a technique! :)
How could you separate a mixture of sand and salt?
toilet paper
